Ecosystem: all the interactions between the living and the nonliving things in an area.
the factors of an ecosystem that are living or used to be living
The biotic factors include: scuba divers, coral (both biotic and abiotic) , sharks, fish, jelly fish, sea turtles, puffer fish, and stingray.
the factors that are nonliving in an ecosystem
The abiotic factors include: the water temperature, sand, how much sunlight, tides, coral which is both biotic and abiotic.
Carrying capacity is the population of a species at its maximum in an ecosystem. The resources needed for a population to survive are; shelter, food, and water.
Why does the population of sharks decrease? -fishing not only to catch fish but also sharks (this is because the shark's food source is being taken away and there are less fish left to eat.)
- and pollution (pollution not only affects the sharks but it affects all other sealife)
Factors in an ecosystem that affect the population of certain organisms because of the availability. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
In the ocean some limiting factors include: shelter, light, and food.
For example.... If the Seahorse eats and lives in the seaweed, but fishers are coming and taking seaweed out of the ocean, and they do this for a while, the seaweed will become a limiting factor for the seahorse. This is because this is his food and shelter that are being taken away and now less are available.
Producers in the ocean:
- seaweed - algae - sponge - plankton
Consumers in the ocean:
- lobsters (carnivores) - shrimp (scavengers) - jellyfish (carnivores) - whales (carnivores)
Decomposers in the ocean:
- hagfish - worms
The producers in the ocean are very important in the ocean ecosystem because they are the base/ starting point of all food chains and food webs. Without them all the other animals would suffer because nothing would ever start the flow energy. Also animals don't only eat the producers in the ocean they use them for shelter.
Food webs are actually more realistic once it comes to an ecosystem because they don't just show the flow of energy through a few organisms, they show the energy flow of multiple organisms. Which means you can fit a whole lot of food chains into one food web.
If you removed the lobster from this food web the sea lion and fish would start to die off, and the organic deposits would over populate. Also the zooplankton would overpopulate because nothing would be eating them.
We use the pyramid rather than other shapes because it shows the flow of energy from one organism to another. The producers are at the base of the pyramid because they have the most energy. Top predators are at the highest level of the pyramid because they have the least amount of energy.
CO2 + H2O ---> C6 H12 O6 + O2
For photosynthesis to occur you need the following: radiant energy (sunlight), carbon dioxide, and water. Photosynthesis produces: glucose, and oxygen.
Photosynthesis takes place in the plant's chloroplasts which is in the leaves.
During the process of photosynthesis carbon dioxide, that us humans breathe out, goes
